Around midday on an unusually chilly day in Florida, Roy Halladay took the mound to throw his first live batting practice of 2013. For Halladay, it seems like any step, however small, in the right direction is a victory after a mediocre 2012 marred by shoulder problems. The former Cy Young winner, at 35, has said he expects to be back at full strength for the start of the season. Halladay faced a quartet of hitters, notably including Chase Utley and Michael Young as Phillies pitching coach Rich Dubee looked on. “Doc was fine,” Dubee said. “Overall, I thought it was a good day of BP today. I thought most of the guys threw pretty well, as far as being in the strike zone, command, that stuff.” Halladay isn’t throwing the entire cupboard of pitches yet. Dubee said Halladay won’t start throwing his curveball for a little while longer. Dubee watched Halladay’s entire session, something he didn’t do with any other pitchers throwing batting practice Monday. The pair chatted afterward and shared a laugh. Dubee added that he’s naturally watching Halladay a little more intently this spring. “Maybe moreso this year, to see how he’s holding his legs, repeating his delivery,” Dubee said. “Today he was pretty good. He was real good.”
